This document describes a new test apparatus and method for rapidly determining the thermoformability of plastic materials. The method involves heating a plastic sheet, stretching it using a plug at forming temperatures, and measuring the forming force versus distance data. This better simulates the actual thermoforming process compared to existing tests. The data generated can be used to compare materials and process parameters, develop a standard thermoformability index, and refine the data into a predictive modeling system. Future work involves developing a standardized thermoformability index and integrating the test data into a predictive modeling program.
The document describes a new thermoformability testing device called Technoform. It aims to address limitations of current testing methods by evaluating materials under conditions that closely mimic the full thermoforming process. Technoform tests specimens through heating, 3D stretching, forming, and cooling. It provides quantitative data on various metrics like sag distance, forming force, and shrinkage. The document outlines Technoform's design and capabilities, and provides several examples showing how it can evaluate the effects of various material and process parameters on thermoformability.

Now-a-days glass fiber-reinforced plastics (GFRP) are always applicable in variety of engineering applications.
It is used in aerospace, automotive and aircraft industries due to their well known properties. Milling of GFRP
composite materials is very difficult due to its heterogeneity and the number of troubles like as surface
delamination during machining affects uniqueness of the material and the machining parameters. Present paper
focuses the experimental details to find out delamination factor on GFRP composite laminates by using
Taguchi‟s DOE L9 orthogonal array. The main objective of the present work is to optimize the process
parameters in the drilling of GFRP composite using Taguchi DOE and to find the significance of each process
parameter using ANOVA. As far as the effect of input factors are considered, the factors drilled material and
spindle speed both have nearly predominant influence on the delamination factor of drilled holes on GFRP
composite by using CNC milling process.
The document summarizes a study that used Taguchi methods and Grey Relational Analysis to optimize machining parameters (cutting speed, feed rate, depth of cut) for turning AISI H13 steel to maximize material removal rate and minimize surface roughness. Experiments were conducted based on an L18 orthogonal array design. Analysis of variance identified the significant parameters affecting each response. Optimal conditions for combined effects were found to be a cutting speed of 270m/min, feed rate of 0.1mm/rev, and depth of cut of 1.5mm, resulting in a surface roughness of 1.0828μm and material removal rate of 554.04mm3/sec.

A new ball burnishing tool was designed and used to burnish aluminum alloy 6061 test samples. The process parameters investigated were burnishing speed, feed rate, force, and number of passes. Experiments were designed using Taguchi's orthogonal array method. Analysis found the optimal parameters for maximum hardness were 250 RPM speed, 0.06 mm/rev feed rate, 8 Kgf force, and 5 passes. Confirmation tests validated these parameters produced the highest hardness of 126 BHN. Hardness was found to generally increase with speed, force, and passes up to certain levels, then decrease with further increases in those parameters. Hard
The document discusses the application of the Taguchi method to optimize parameters for the filament winding process of producing thermoplastic composite tubes. Four factors were examined - fiber temperature, winding speed, number of layers, and number of roving. Experiments were conducted according to an L9 orthogonal array, resulting in 9 composite tubes being produced and tested for tensile and shear strength. Analysis of the experimental data found that fiber temperature and number of layers most significantly affected tensile strength, and should be set at 230°C and 4 layers respectively to maximize strength. The Taguchi method was able to determine optimal process parameters while requiring relatively few experimental runs.

High Strain Rate Testing of Materials
Polymers, composites and some metallic materials are viscoelastic and strain-rate sensitive. Under high strain rates the micro mechanisms by which these materials deform is different than that experienced at low strain rates. Consequently, use of quasi-static stress-strain data may not produce accurate and reliable predictions, when such data is used in simulation and Finite element analysis FEA of engineering components.

IRJET- Effect of Layering on Thermal Comfort of NonwovensIRJET Journal
This document studies the effect of layering on the thermal comfort properties of nonwoven fabrics. Four nonwoven fabric samples were produced with a varying number of layers (1 to 4 layers) but keeping the final gram per square meter (GSM) the same. Thermal properties including thermal insulation value (TIV), clo value, and water vapor transport rate were tested. The results showed that increasing the number of layers significantly improved the TIV and clo values due to an increase in the quantity of trapped air pockets. However, the maximum temperature felt (q-max) remained the same. Water vapor transport rate generally decreased with more layers due to separation of layers forming discontinuous channels, except for one sample where needle placement
Experimental Study of Pervious Concrete with Polypropylene FiberIRJET Journal

This document summarizes a study that used the Taguchi method to investigate optimal process parameters for tool wear in hard turning of AISI H11 steel. Three factors (tool material, hardness, and speed/feed) were examined at three levels each in an L9 orthogonal array. Tool wear was measured and transformed to a signal-to-noise ratio to determine the optimal level combination. Analysis of variance was also used to determine the influence of each factor on tool wear. The results identified the best levels for minimizing tool wear in hard turning of hardened steel.
This document describes a study that used the Taguchi method to optimize cutting parameters for milling glass fiber reinforced plastic (GFRP) composites. Experiments were conducted using a Taguchi L27 orthogonal array to examine the effects of fiber orientation angle, helix angle, spindle speed, and feed rate on surface roughness, machining force, and delamination. Regression analysis and analysis of variance were used to develop a mathematical model relating the responses to the cutting parameters and determine significant factors. The goals of the study were to minimize the responses and establish correlations between cutting parameters and machining performance of GFRP composites.
The document presents the results of an experimental investigation comparing the surface quality of different glass fiber reinforced plastic (GFRP) composites when undergoing end milling. Specifically, it examines the effect of cutting parameters like spindle speed, feed rate, and depth of cut on the resultant force, surface roughness, and delamination of uni-directional and bi-directional GFRP laminates milled with a solid carbide end mill. The experiments were designed using Taguchi methods and analyzed to determine the most significant parameters and draw conclusions about the machinability of different GFRP materials.

Effect of High Temperature on Compressive Strength of ConcreteIOSR Journals
This document summarizes research on the effect of high temperatures on the compressive strength of concrete. Ninety concrete cubes were cast in three grades and subjected to temperatures from 200°C to 800°C for 1-2 hours. Testing found that strength was largely unaffected up to 350°C but started declining at 500°C, with over 30% reduction at 650°C. Beyond 650°C, concrete was largely decimated. Higher exposure times and temperatures led to greater strength reduction. The research adds to understanding concrete performance in fire conditions and suggests serviceability may be maintained up to 500°C but major repair is needed over 650°C.
Effect of varying temperatures on the quality of concrete with 5% addition of...McKevin Ramduma
The high rate of building collapse in Nigeria has been a source of concern to
professionals and stakeholders in the building construction industry. Research has
shown that 100% of buildings collapsed in Nigeria were made from reinforced
concrete (Lekan, 2011). Cement which is a main binder in concrete production is
expensive particularly in developing countries like Nigeria, therefore increasing the
demand to explore pozzolanic potentials of clay. In the local construction industry,
shabby construction practices such as mixing concrete on the bare ground or the
deliberate addition of clay to concrete has effect on the properties of such concrete.
Fire hazards subject concrete structures to high temperature conditions which lead to
uneven expansion of the structure, causing cracks and eventually, failure of the
structure. High temperatures have effect on concrete properties such as appearance,
durability and compressive strength. Though extensive research has been done on the
effect of clay impurities on various properties of concrete, this project aims at
assessing the effect of varying temperatures on the properties of concrete containing
clay addition.
Fifteen 150mm×150mm×150mm samples of concrete cubes of mix ratio 1:2:4,
water/cement ratio of 0.45 and 5% clay addition were cast and cured for 28 days.
After curing, the samples were subjected to varying temperatures (100°C, 200°C,
300°C, 400°C and 500°C) and crushed. The findings from the results of the experiment
revealed that, concrete cube samples subjected to temperatures above 400°C failed to
meet the required 21N/mm2 compressive strength for normal weight concrete used for
structural purposes.

Dale Carnegie was an American author who wrote the iconic self-help book "How to Win Friends and Influence People." Published in 1936, the book became a massive bestseller and has sold over 30 million copies worldwide. The book provides timeless advice on effective communication and positive relationships that remain highly relevant today. Some of Carnegie's key principles included avoiding criticism, making others feel important, appealing to people's interests and motivations, and using tact and diplomacy rather than confrontation. Business magnate Warren Buffett was highly influenced by the book in his early career.
Strain gauges measure strain on an object by detecting changes in electrical resistance when the object is deformed. The document discusses various types of strain gauges and their components.

GROUP PROJECT Mini open-ended project aerolab 1nikadam468
This project compares the thermal properties of 3D printed engine block prototypes made of PLA and PETG plastic materials. Specimens of each material were 3D printed and their thermal conductivity measured using a linear heat conduction test. The experimental results found that PETG had a higher thermal conductivity of 21.67 W/mK compared to 33.22 W/mK for PLA, opposite of the typical values. However, the results were not considered reliable due to errors in the 3D printing dimensions, imperfect surface contact, and insufficient power for the test. While the objectives of identifying and comparing the materials' thermal properties were achieved, the experimental method needed improvements to produce more accurate measurements.

Thermal analysis techniques such as differential scanning calorimetry (DSC) are used to investigate polymer properties as a function of temperature. DSC provides information on glass transition temperatures, crystallization temperatures, melting points, and heat capacity by measuring the heat flow into or out of a small polymer sample as it is heated or cooled. Proper sample preparation and experimental parameters are important to obtain accurate and reproducible DSC results.
Advanced Polymer Nanocomposites for 3D printing in SpaceColeman Fincher
Space and at-sea environments pose significant challenges due, in part, to logistics associated with repair and replacement of worn or damaged equipment. These technical and economic challenges may be significantly mitigated through the use of Additive Manufacturing (AM), specifically Fused Deposition Modeling (FDM) 3D printing, as a method to produce desired repair parts at the point of usage. However, most state-of-art polymers generally employed in AM possess relatively low melting points and poor ratings in terms of fire, smoke, and toxicity.
We have developed an FDM filament and modifications to an existing FDM process to allow printing of thermally stable and flame resistant polymeric parts.
Thermal analysis characterization of polymers and plastics acs webinarKevin Menard, Ph.D. MBA
Thermal analysis is a collection of techniques that examines how polymer properties change with temperature. Common techniques include DSC, TGA, DMA, and TMA. DSC measures transitions like glass transition and melting points via changes in heat flow or temperature. TGA analyzes weight changes with rising temperature such as decomposition. DMA provides storage modulus and damping curves to identify transitions. Thermal analysis is useful for characterizing polymers, determining purity, and studying curing and degradation. Hyphenated techniques like TG-IR and TG-GCMS further identify materials and products evolved during thermal degradation.

This document provides a review of special variants of the hot embossing process for polymer microfabrication. It describes rapid-thermal-response embossing, which uses a low thermal mass mold to allow extremely rapid heating and cooling and significantly reduce cycle times. Room-temperature embossing is also reviewed, which deforms polymers in the solid state at low temperatures to eliminate cooling. Two-station embossing employs two mold bases, one hot and one cold, to approximate decoupled heating and cooling. Localized embossing locally melts and deforms features on thick polymer substrates to improve replication quality and accuracy. These variants aim to improve productivity, replication fidelity and expand the range of materials suitable for embossing
Several Kinds of Thermal Analysis Technologies of Measuring Glass Transition ...IJERA Editor
Thermal analysis technology is a general term of a set of techniques that can measure the material’s performance varying with temperature. The thermal property, volumetric property, mechanical property and electrical property of polymer exist obvious difference through glass transition, tracking these properties’ variation with temperature changes can determine its GTT (glass transition temperature). According to different measuring principles, these thermal analysis technologies of testing GTT are divided into following several categories, they are differential scanning calorimetry (DSC), differential thermal analysis (DTA), modulated differential scanning calorimetry (MDSC), thermo-mechanical analysis (TMA), dynamic thermomechanic analysis (DMA) and dielectric thermal analysis (DEA). The article introduces their testing methods, characteristics and influencing factors, in order to provide a reference for choosing appropriate technique to measure the glass transition temperature.

Investigation of Tribological Behaviour of GF Filled Peek Composite under the...IJERA Editor
Composite materials have successfully substituted the traditional materials in several light weight and high
strength applications. The reasons why composites are selected for such applications are mainly their high
strength-to-weight ratio, high tensile strength at elevated temperatures, high creep resistance and high
toughness. Therefore minimum Wear of component or part used in machinery is very important factor for the
industry. In this paper the tribological behavior of PEEK (Poly-ether-ether-ketone) composites reinforced by
30% short glass fiber and phosphor bronze were comparatively evaluated on Pin on disc machine. The effect of
three parameters such as temperature, load and sliding distance on Wear loss of PEEK composites reinforced by
30% short glass fiber and phosphor bronze were examined. The detailed mathematical model is simulated by
Minitab 17 and simulation results fit experiment data very well
In this investigation, an effective approach based on Taguchi method, analysis of variance (ANOVA),
multivariable linear regression (MVLR), has been developed to determine the optimum conditions leading to
minimum Wear. Experiments were conducted by varying temperature, load and sliding distance using L9
orthogonal array of Taguchi method. The present work aims at optimizing process parameters to achieve
minimum Wear. Experimental results from the orthogonal array were used as the training data for the MVLR
model to map the relationship between process parameters and Wear. The experiment was conducted on
computerized Pin on Disc machine. It was observed that PEEK 30% Glass Fiber Composite Polymer has
excellent wear resistance compare to Phosphor bronze at elevated temperature.
Study On The External Gas-Assisted Mold Temperature Control For Thin Wall Inj...IJERA Editor
Dynamic mold surface temperature control (DMTC) has many advantages in micro-injection molding as well as thin-wall molding product. In this paper, DMTC will be applied for the thin-wall molding part with the observation of the weldline appearance and the weldline strength. The heating step of DMTC will be achieved by the hot air flow directly to the weldline area. The results show that the heating rate could be reached to 4.5C/s, which could raising the mold surface from 30C to over 120C within 15 s. The melt filling was operated with high temperature at the weldline area; therefore, the weldline appearance was eliminated. In addition, the weldline strength was also improved. The results show that the thinner part had the higher strength of the weldline.
High heat resistance is ULTEM™ resin’s signature property. But there’s a lot to understand about short- and long-term temperature performance—and how it applies to different industries and applications.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
